Forexample, the touch sensor unit 121 may receive operation signals by auser's hand or a physical tool, a stylus pen, an operation button thatmay be included in the stylus pen, etc.

The voice sensing sensor unit 122 may automatically sense an externallygenerated voice. When a voice is externally generated, the voice sensingsensor unit 122 may transmit the voice to the controller 130 so that theterminal 100 may operate at the voice sensing mode. If the mode ischanged to the voice sensing mode by the voice sensing sensor unit 122,the terminal 100 may receive a voice through the voice input unit 112.

The controller 130 may control each of various components for overalloperation of the terminal 100. For example, the controller 130 mayrecognize a situation by analyzing a sensed voice, and control theterminal 100 to block the function of the terminal 100.

The controller 130 may includes a voice analysis unit 131 and a contextawareness unit 132.

If the voice sensed in the voice sensing sensor unit 122 is inputtedthrough the voice input unit 112, the voice analysis unit 131 mayanalyze the voice. The voice analysis unit 131 may analyze at least oneof a pitch, format and amplitude of the voice. The pitch may indicateperiodic characteristics of the voice. The voice analysis unit 131 mayanalyze periodic characteristics of the time axis using anauto-correlation function or may analyze periodic characteristics of thefrequency axis by acquiring the basic frequency based on the frequencyelements as a result of FFT.

According to an embodiment of the present invention, the storage unit140 may store generated owner voice information based on the result ofanalysis on the owner voice analyzed through the voice analysis unit 131for the voice of the owner inputted through the voice input unit 112.

Further, according to an embodiment of the present invention, thestorage unit 140 may store a predetermined arbitrary control operationbased on the recognized context. That is, when an arbitrary situation(context) is recognized, the storage unit 140 may preset and storecontrol operation that may be performed by the terminal 100.

The display unit 150 displays (outputs) information processed in theterminal 100. For example, the display unit 150 may display a userinterface or a graphic user interface related with voice sensing,context awareness and function control.

The display unit 150 may operate as a touch screen by forming a layerstructure with a touch sensor unit 121. Here, the display unit 150 mayalso be used as an input device as well as an output device.

The touch sensor unit 121 may convert a change such as pressure andcapacitance applied to a certain area of the display unit 150 into anelectric input signal. The touch sensor unit 121 may be configured todetect a touch pressure as well as a touched location and area.

Components illustrated in FIG. 1 are not essential, and thus more orless components may be used to implement the terminal 100.

FIG. 2 is a flowchart illustrating a method of inputting a voice of aterminal owner and setting a control operation according to the presentinvention.

Referring to FIG. 2, the owner voice input and control operation settingmethod may be performed in an order described below.

First, the terminal 100 may determine whether a voice input request hasbeen generated (210).

The voice input request is a request for inputting a voice of the ownerof the terminal 100, and may be generated according to user's request orautomatically as is necessary. The terminal 100 may display an icon, amenu, etc. for receiving a voice input request.

If a voice input request is generated, the terminal 100 may receive aninput of the voice of the terminal owner (220).

The terminal 100 may display an icon, image, UI or GUI, etc. fornotifying a state where a voice is being inputted or a state where avoice is possible while a voice of the terminal owner is being inputted.For example, referring to FIG. 3, the terminal 100 may display an imageof a microphone shape and/or an icon (e.g., 0, etc.), a text image(e.g., REC, etc.) indicating that a voice is being inputted.

When a plurality of owners for the terminal 100 are recognized, theterminal 100 may receive an input of a voice for one of the owners. Inthis case, the terminal 100 may receive identification information ofthe owner. When the identification information of the owner is notreceived or it is impossible for the identification information to bereceived, the terminal 100 may set arbitrary identification informationfor the owner.

Next, the terminal 100 may analyze the owner's voice (230).

The terminal 100 may analyze the inputted voice of the owner. Theterminal 100 may analyze at least one of a pitch, formant and amplitudeof a voice of the owner. The terminal 100 may analyze periodiccharacteristics of the time axis using an auto-correlation function ormay analyze periodic characteristics of the frequency axis by acquiringthe basic frequency based on the frequency elements as a result of FFT.The terminal 100 may analyze the format frequency by specifying byspecifying the area where energy of a voice is concentrated in thefrequency domain. Further, the terminal 100 may analyze amplitude bysampling and acquiring the size by quantization and encoding.

The terminal 100 may analyze the gender, age, etc. of the terminal ownerthrough voice analysis.

The terminal 100 may perform a separate process such as a noiseelimination and sound amplification in order to increase accuracy forthe analysis of the owner's voice. Next, the terminal 100 may storevoice information of the owner (240).

The terminal 100 may store the owner's voice information based on theresult of analysis. The owner's voice information may contain the pitch,formant, amplitude of the acquired voice, gender and age of the personwho generates the voice, etc. The terminal 100 may store the voiceinformation of the owner in the form of a graph, digital data, analogdata, numbers, etc. according to the frequency or time domain.

When a plurality of owners of the terminal 100 are recognized as isnecessary, the terminal 100 may store voice information for a pluralityof users. At this time, the terminal 100 may store voice information foreach user along with identification information for a plurality ofusers.

The terminal 100 may determine whether a control operation settingrequest has been generated (250).

The terminal 100 may determine whether a control operation settingrequest for an arbitrary recognized context has occurred. The controloperation setting request may occur according to user's request orautomatically as is necessary. For example, the control operationsetting request may automatically occur after a voice input of the owneraccording to the voice input request.

When the control operation setting request occurs, the terminal 100 mayreceive an input of the control operation (260).

The terminal 100 may display a list, icon, related UI or GUI ofrecognized context in order to receive a control operation setting.Further, the terminal 100 may display a menu, a control operation list,icon, related UI or GUI for receiving an input of the control operation.For example, referring to FIG. 4, the terminal 100 may display a lockingmode, an alarm restriction, a data display restriction, a data deletion,etc. in a list as a control operation according to selection of a casewhere the recognized context is a situation of use of a user who is nota terminal owner. Further, the terminal 100 may display an icon and acheck box according to user's selection input or current controloperation setting state, or shaded control operation.

The terminal 100 may receive control operation for the recognizedcontext (situation) of the terminal 100. The recognized context may beone of whether used by the owner, whether used by an adult or a child,and whether used by a man or a woman. The terminal 100 may receivedifferent control operation according to the context. Next, the terminal100 may set control operation (270).

The terminal 100 may set control operation to be performed according tocontext awareness based on the inputted control operation. The controloperation may include at least one of locking mode setting, an alarmblock, a certain function use block, a data display block, datadeletion.

The terminal 100 may set control operation for the recognized context ofthe terminal 100. The recognized context may be at least one of whetherused by the owner, whether used by an adult or a child, and whether usedby a man or a woman. The terminal 100 may receive different controloperation according to the context. The terminal 100 may set differentcontrol operation according to the context.

When a plurality of owners of the terminal 100 are recognized, theterminal 100 may differently set control operation for each owner.

When there is no control operation setting request, the terminal 100 mayset the control operation as default (280).

For example, when the terminal 100 is not being used by the owner, theterminal 100 may be set to perform control operation that sets thelocking mode as default. Further, when the terminal 100 is used by achild, the terminal 100 may be set to perform control operation thatblocks the use of an application and keypad function that is charged asdefault.

FIG. 5 is a flowchart illustrating a method of controlling a terminalusing context awareness according to the present invention.

Referring to FIG. 5, a method of controlling a terminal using contextawareness may be performed in an order described below.

First, the terminal 100 may recognize whether a voice is sensed (310).

The terminal 100 may sense whether a voice is externally sensed troughthe voice sensing unit 122. The sensed voice may be a user's voice ofthe current terminal including the owner.

When the voice is sensed, the terminal 100 may analyze the voice (320).The terminal 100 may analyze the sensed voice. The terminal 100 mayanalyze at least one of a pitch, formant, amplitude of the sensed voice.The terminal 100 may analyze periodic characteristics of the time axisusing an auto-correlation function or may analyze periodiccharacteristics of the frequency axis by acquiring the basic frequencybased on the frequency elements as a result of FFT. The terminal 100 mayanalyze format frequencies by specifying the area where energy of avoice is concentrated in the frequency domain. Further, the terminal 100may analyze amplitude by sampling the voice signal and acquiring thesize by quantization and encoding.

The terminal 100 may analyze the gender, age, etc. of the current userof the terminal 100 through sound analysis.

The terminal 100 may perform a separate process such as a noise removal,sound amplitude, etc. in order to enhance accuracy for the soundanalysis of the owner.

The terminal 100 may sense the sound during the calling functionperformance and analyze the sensed sound.

Specifically, referring to FIG. 6, the terminal 100 may perform acalling function (321).

The terminal 100 may perform an outgoing call according to user'srequest or may perform an incoming call according to a receivingallowance request of user for a received call.

Next, the terminal 100 may sense the voice (322).

The terminal 100 may sense voice externally generated during performanceof a calling function. At this time, the sensed voice may be a user'svoice for performing a call. The sensed voice may be transmitted to thebase station through the signal processing according to the performanceof a calling function so as to be transmitted to the calling opponentterminal. Further, the sensed voice may be sampled or recorded accordingto whether a function additionally provided along with the callingfunction is used.

Next, the terminal 100 may determine whether the calling has beenterminated (323). The terminal 100 may determine whether the calling isterminated as the user's request or the signal transmission andreception with the base station becomes impossible.

When the calling is not terminated, the terminal 100 may continuallysense the voice. In contrast, when the calling is terminated, theterminal 100 may analyze the lastly sensed voice (324).

The terminal 100 may analyze the voice sensed right before the lastsensed voice, i.e., termination of the calling. As such, the terminal100 may determine whether the terminal 100 has been terminated toanother user, not the owner, right before the termination of thecalling. The function restriction for privacy protection may be achievedwhen a user other than the owner of the terminal 100 tries to use otherfunctions of the terminal 100.

Next, the terminal 100 may recognize context (330).

The terminal 100 may recognize the current situation of the terminal 100based on the result of analysis of the voice. The terminal 100 mayrecognize the owner's situation of use based on the result of voiceanalysis. Further, the terminal 100 may recognize at least one ofwhether used by the owner, whether used by an adult or a child, andwhether used by a man or a woman.

Specifically, referring to FIG. 7, the terminal 100 may recognizewhether the terminal 100 is being used by the owner (331).

The terminal 100 may recognize whether the current terminal 100 is beingused by the owner based on the result of voice analysis. That is, theterminal 100 may determine whether the sensed voice is the voice of theowner. The terminal 100 may recognize whether the terminal is used bythe owner by determining whether the sensed voice coincides with thevoice information of the owner as a result of analysis based on thepre-stored owner's voice information.

When the terminal is not being used by the owner, the terminal 100 mayrecognize whether the terminal is used by an adult or a child (332). Theterminal 100 may determine whether the current user of the terminal 100is an adult or a child. The terminal 100 may apply a preset thresholdvalue to the result of analysis in order to determine whether user is anadult or a child. For example, if the pitch is larger than the thresholdvalue as a result of the voice analysis, the terminal 100 may determinethat the user of the current terminal 100 is a child.

The terminal 100 may recognize whether the terminal 100 is being used byan adult or a child regardless of whether the terminal 100 is being usedby the owner as is necessary. Further, the terminal 100 may recognizewhether the terminal is being used by a man or a woman (333).

The terminal 100 may determine whether the current user of the terminal100 is a man or a woman. The terminal 100 may apply a preset thresholdvalue to the analyzed result in order to determine whether user is a manor a woman. For example, as a result of the voice analysis, if the pitchis greater than the threshold, the terminal 100 may determine that theuser is a woman.

The terminal 100 may recognize one situation or a combination of two ormore situations. For example, the terminal 100 may recognize whether thecurrent user of the terminal 100 is a man.

Next, the terminal 100 may perform control operation (340).

The terminal 100 may perform control operation based on the recognizedcontext (situation). The control operation may include at least one oflocking mode setting, alarm blocking, certain function use blocking,data display blocking, and data deletion. The control operation may bepreset as a default that is provided by user or in the terminal 100.

Specifically, the control operation may be an operation that sets thelocking mode. For example, referring to FIG. 8, as a result of the voiceanalysis, if the terminal 100 is being used by the owner of the terminal100, the locking mode of the terminal 100 may be set. The terminal 100may set the screen off mode, power-save mode, power off mode, etc.instead of setting the locking mode. The terminal 100 may display thelocking release UI, the password input UI, the pattern input UI, etc.according to the locking mode.

If the user including the owner of the terminal 100 inputs a password orpattern for releasing the locking mode, the terminal 100 may cancel thelocking mode and allow the use of the terminal 100.

Further, for example, referring to FIG. 9, the terminal 100 may analyzethe voice based on the voice recognized during the calling functionperformance, and when it is recognized that the user, not the owner,uses the terminal 100 at the time of terminating a call as a result ofanalysis of the voice, the locking mode may be set. As such, theterminal 100 may release the locking mode for calling, and may preventanother user from using the function of the terminal 100 according tothe locking mode release state after the termination of a call.

The control operation may be an operation for blocking the alarm.

The terminal 100 may block the alarm on reception of a text message, ane-mail, a phone call, a mobile messenger message, etc. based on therecognized situation. The object for blocking the alarm may be set inadvance by the user. The terminal 100 may block an unconfirmed textmessage, an unconfirmed e-mail, an unconfirmed mobile messenger message,an alarm for existence of a call during absence as well as a textmessage, an e-mail, a phone call, a mobile messenger message, etc. whichare received in real time. Further, the terminal 100 may block an alarmfor a text message, an e-mail, a phone call, and a mobile messengermessage which are received from a certain user using information storedin a phone book. The terminal 100 may block an alarm displayed on thedisplay unit 150 as well as an alarm that outputs vibration, sound, etc.

For example, referring to FIG. 10, as a result of analysis of the voice,when it is recognized that user who is not the owner is using theterminal, the terminal 100 may block an alarm on whether a text messagehas been received or there has been a phone call during absence.

The control operation may be an operation that blocks a use of a certainfunction.

The terminal 100 may block a use of an application and a service whichare provided in the terminal 100 based on the recognized context.Further, the terminal may block a use of an application, a service or atouch input which is charged, a keypad operation, a correction forarbitrary data, and a use of a deleting function.

For example, referring to FIG. 11, as a result of voice analysis, whenit is recognized that the user who is not the owner uses the terminal100, the terminal may block the use of a certain application.

At this time, the terminal 100 may display a message, icon, image, UI orGUI indicating that a use of an application has been blocked. Theterminal 100 may output a pop-up window, an alarm window, a sound, etc.in order to notify that a use of an application has been blocked.

Further, for example, when it is recognized that the terminal is beingused by a child who is not the owner, a calling function, a game and ause of an application that is charged may be blocked. Further, theterminal 100 may prevent a situation where the terminal 100 isarbitrarily operated by a child by blocking a use of a touch input or akeypad operation.

The terminal 100 may store information for a function such as anapplication and a service provided by the terminal 100 in order to blocka use of a certain function. For example, the terminal 100 may storeinformation on a function such as the name of the function, theidentifier, the location of the function execution file, supplierinformation and whether there is a function that is charged.

The control operation may be an operation that blocks a data display.

The terminal 100 may block a display of part or whole of data for aphone number, calling details, a text message list, an e-mail list, aphoto album, a memo, etc. stored in the terminal 100 based on therecognized situation. Further, the terminal 100 may block a display ofan icon, a menu, widget, UI, GUI, contents, etc. which are set to bedisplayed on the screen. The data that blocks the display may be set inadvance by user. The data that blocks the display may be set for acertain application or service such as a phone number, a photo album, amemo, etc. or may be individually set for data within a certainapplication or service.

The terminal 100 may rearrange a list or icons on a standby screen fordata other than data whose display has been blocked. That is, the layoutof the displayed data may be rearranged and displayed so that thelocation of the blocked data is not displayed empty. For example,referring to FIG. 12, when it is recognized that a user other than theowner is using the terminal as a result of the voice analysis, theterminal 100 may block a display for a part of information stored in thephone number list.

Further, for example, referring to FIG. 13, when it is recognized that auser other than the owner is using the terminal 100 as a result of thevoice analysis, a display of a part of icons which are set to bedisplayed on a standby screen may be blocked.

The terminal 100 may block a display of data in connection with theblocking of a use of a certain function. For example, when it isrecognized that the terminal 100 is being used by a child, the terminal100 may block a use of a calling and game application. Further, theterminal 100 may block a use of an application by blocking a display ofan icon of a calling and game application that is displayed on a standbyscreen.

The control operation may be a data deleting operation.

The terminal 100 may delete data stored in the terminal 100 based on therecognized context. The terminal 100 may delete history data including arecent use record, a list of an application or execution file that isunder operation, a calling record, and a purchasing record. Further, theterminal 100 may delete part or whole of data for a phone number, acalling record, a text message list, an e-mail list, a photo album, amemo, etc. which are stored in the terminal. Here, the terminal 100 mayprevent an output of important data when the terminal 100 is lostthrough data deletion.

For example, referring to FIG. 14, when it is recognized that a userother than the owner uses a terminal 100, the terminal 100 may delete ahistory list of recently operated applications.

The control operation of the above-described terminal 100 is not limitedto one operation, but may be operated by combining two or moreoperations according to a setting state inputted at the time ofmanufacturing the user's input or terminal 100.
